Zlib not found on Fedora 28

[pshem]

I was following the build guide from https://github.com/rumpkernel/wiki/wiki/Repo:-rumprun

Trying to build rumprun gets me:

$ ./build-rr.sh hw
>>
>> NOTICE: Not a buildrump.sh-based git repo in <redacted>/rumprun/src-netbsd
>> Cannot verify repository version.  Proceeding ...
>>
>> ERROR:
>> Host zlib (libz, -lz) required, please install one!

This is despite zlib being already installed: (Src-netbsd contains a bunch of folders and a Makefile, as I'd expect after cloning it by initialising submodules)

sudo dnf install zlib

Package zlib-1.2.11-8.fc28.x86_64 is already installed, skipping.
Dependencies resolved.
Nothing to do.
Complete!

Am I missing something?

On Ubuntu 18.04 you need zlib1g-dev, on Fedora 28 you need zlib-devel.
